In their defense of the franchise's first World Series title, the Houston Astros are currently slated to finish with the best overall record in baseball, according to Westgate Las Vegas Superbook.

The Astros' over-under win total is set at 96 1/2. Right behind the defending champions, the Los Angeles Dodgers - who lost to Houston in the Fall Classic - and the Cleveland Indians are set at 95 1/2.

Just behind the upper-tier teams, the New York Yankees and Washington Nationals round out the top five, with both sitting at 94 1/2.

On the other side of the table, the Miami Marlins are the consensus last-place team, set dangerously close to a 100-loss campaign with an over-under of 64 1/2 wins. The Detroit Tigers are the only other team expected to win fewer than 70 games with a 67 1/2 over-under win total.
